The LT3745EUJ-1#TRPBF is a high-performance, flexible, single-channel LED driver. It has been designed to power high-brightness LEDs in automotive, home lighting, audio and signage applications. With its high-efficiency, high switching frequency and low quiescent current, the LT3745EUJ-1#TRPBF is an excellent choice for driving single-channel LED applications.

The LT3745EUJ-1#TRPBF is a flexible LED driver with adjustable output current. Its flexible current regulation can be configured to provide power savings by dimming the LED output current. The output current is set with a single external resistor, which is adjustable over a wide current range from 50mA to 2000mA. The regulator also features a low quiescent current of only 30μA, enabling it to be powered from a small battery or other low-current power sources.

The LT3745EUJ-1#TRPBF uses an easy-to-use control interface, allowing it to be operated in an open or closed loop. In open loop mode, the output current is set by a voltage ramp provided by the external resistor. This allows the LT3745EUJ-1#TRPBF to be quickly adjusted for different output current levels. In closed loop mode, the output current can be regulated from the feedback signal from an external Hall-effect device. This allows for more precise current control and longer battery life.

The LT3745EUJ-1#TRPBF also features programmable over-temperature, over-current and over-voltage protection, as well as soft start and active current sharing capabilities for multiple strings of LEDs. The device is rated for operating temperatures from -40°C to +125°C, making it suitable for automotive, industrial, and outdoor applications.

The LT3745EUJ-1#TRPBF is an excellent LED driver for applications that require high-efficiency, high switching frequency, and low quiescent current. Its wide input voltage range, adjustable current limit, and multiple protection features make it an ideal choice for driving single-channel LED applications in automotive, home lighting, audio, and signage applications.
